This invention relates to devices for use in setting a liner tip in themold slot of an integral line-casting type machine and'particularly tosimple and inexpensive means adapted for this purpose when the mold slotis of any desired width for forming any desired size of type body.

On integral line type-casting machines the length and size of type linesare regulated by interchangeable steel blocks called liners.

A so-called poor mans liner has been in common use in printing plantsfor years as an emergency substitute and also for economy's sake.

Such liners are formed by positioning a steel member such as a 30-picaliner in the mold slot adjacent one end thereof, placing a steel linertip in the mold slot at the proper distance from the opposite endthereof and bonding the 30- pica liner and liner tip together with typemetal by the first casting operation.

Because of the contraction of type metal in commercial use (theory tothe contrary), and because of warpage of the mold cap, it is a luckyfeat to set the steel tip in the mold slot with hope of any degree ofaccuracy in the final product using the crude means at the disposal of alinotype operator.

It is with the problem of warpage and of shrinkage that this inventionhas to deal in setting a liner tip. In the event of a warped mold cap,the cap, warped in a slight upward bow with its ends resting on aconstant liner and a 30-pica liner of the same body, will not clamp aliner tip of the same body and hold it firmly for the first binding castof the machine.

The alternative which the invention proposes to provide for the purposeof overcoming these difficulties is to use a tip and a constant liner ofthe type body desired and a 30-pica liner of less thickness, permittingthe'mold cap to rest on and hold the tip firmly, which will produce thedesired type line. There is no demand for accuracy in the type metalused as a binder for the tip, for its sole usefulness is as a binder andit is thrown aside when a new setting of the tip is desired.

Among the principal objects of the present invention are to providemethods and means for accurately setting the liner tip in the mold slotin any desired position; to provide simple and inexpensive means adaptedfor use in setting the liner tip, and to overcome the difficultiespresented by warping of the mold cap and shrinkage of the type metal.

The accompanying drawing shows the essential features of the inventionand their relation to the old structure and connection therewith:

Fig. 5. Elevation of poor mans liner, a fabrication composed of the30-pica liner 4, binding metal 12, liner tip 5.

A detailed explanation follows:

With the invention used as a guide it is possible to set a liner tip ofthe smallest and tips for all larger size type bodies, for its greatestthickness is less than the thickness of the smallest commonly used typebody.

To set a 5 -point tip to produce the product of an all-steel liner 9 emslong, move the scale in its holder until the 9 scribe registers with thescribe on the beveled window ledge of the holder 8, as shown in Fig. 1.

The lug 9, Fig. 2, is inserted in the liner recess 6, Fig. 3, with theprojections 1 of the holder on either side of the liner stop andadjacent the recess 6. The 5 -point liner tip 5, Fig. 4, is theninserted in the mold slot, using the square edge formed by theprojecting L-shaped portion at the end of the scale as a guide.

The mold-cap 2 is clamped in place, the invention removed and a 5-point3-pica liner is inserted in its place at 6 and jacked up to the moldcap,shutting oiT the approximate .085 inch space above the 5-point BO-picaliner with a sliver of type metal picked from the floor, and typesettingcan proceed. The method, with graduated uniformity, is to be'used forlarger sized type bodies.

I claim:

1. A device for setting a liner tip in the mold slot of an integralline-casting type machine comprising a member formed with means thereonfor engaging a recess in the mold slot to hold said member in fixedposition with respect thereto and an element movable with respect tosaid member and graduated to indicate the relative positions thereof,said element having a portion formed to engage a liner tip to positionthe same. 55

2. A device for setting a liner tip in the mold slot of an integralline-casting type machine comprising a member formed with means thereonfor engaging a. recess in the mold slot to hold said member in fixedposition with respect thereto and an element slidably mounted on saidmember and graduated to indicate the position thereof, said elementhaving a portion thereof formed to engage a. liner tip to position the10 same.
